AUTOMOBILE-JACK.

Specification of Letters Patent.

Patented July 27, 1915.

Application filed August 26, 1912, Serial No. 717,145. Renewed June 4, 1915. Serial No. 32,245.

To all whom it may concern: Be it known that I, EDWARD H. FRANK, a @itizen of the United States, residing at Centralia, in the county of Marion and, State of Illinois, have invented a new and useful Automobile-Jack, of which the following is a specification.

The device forming the subject matter of this application is a jack adapted to be employed for elevating aut omobiles and like vehicles in a garage, to the end that the tires upont-he vehicle wheels 'maV. not be subjected to the weight of the car, while the car is standing in the garage and is not in use.

The invention further aims to provide novel means for engaging portions of the vehicle to support the same, and to provide novel mechanism whereby the supporting means may be elevated readily from an accessible point, and by a single person.

Vith the foregoing and other objectsin view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawings, Figure 1 shows the invention in top plan; Fig. 2 is a side elevation; Fig. 3 is a side elevation of one of the a casings and the adjacent parts; Fig. 4. is an elevation of the casing, viewed at right angles to the View point in Fig. 3; Fig. 5 is a side elevation of one of the rack bars.

In carrying out the invention there is provided a support 1 which may be of any form, the same being, if desired, the floor of a garage. Spacing blocks 2 are connected with the support or foundation -1, the spacing blocks 2 upholding a platform, which may be of the form of spaced tracks 3, inclined to one end, as indicated at 3, to fatcilitate the placing of the car upon the tracks.

Fixed to and upstanding from the support or foundation 1 are standards 4, in which is ournaled for rotation a drive shaft 6, extended substantially parallel to the tracks 3, the drive shaft 6 being equipped at one end with a hand wheel 7 or like device, whereby rotary movement may be imparted manually to the drive shaft. Fixed to the drive shaft 6 are vertical pinions 8, meshing into horizontal, beveled pinions 9, fixed to the upper ends of auxiliary shafts 10, the auxiliary shafts being journaled for rotation in standards 4:. Secured to the lower portions of the auxiliary shafts 10 are horizontally disposed beveled pinions 1 1, meshing into vertically disposed beveled .pinions 15, carbrackets 11 and 12 which are secured to the i ried by'the supplemental shafts 16 located below, and extended transversely of, the tracks 3, the supplemental shafts 16 being journaled in the rings 17 which are carried by the support 1. The free extremities of the supplemental shafts 16 may be journaled I in bearings 18 fixed to the support 1.

The invention further includes a pluralitV of casings 19 which may be located as desired, with respect to the tracks 13. As shown, one pair of the casings 19 is located upon the outside of the tracks, so? that cer-- V Each casing 18 is provided with a longitudinal partition 20, dividing the casing 1nto a compartment 22 and into another compartment 21. Stub shafts 23 are mount ed for rotation in the casings 19, thestub shafts 23 carrying worm wheels 24: which are located in the compartments 22, worm' wheels 24 meshing into worms 25 which are carried-by the supplemental shafts 16, the

' shafts 16 being journaled in the casings 18.

Each stub shaft 23 carries a. pinion 26 which meshes into a rack 27, formed upon a bar 28 mounted to slide vertically in the compartment 21, each bar 28 being provided at its upper end with a crutch 29 constructed to engage any suitable or accessible portion of the vehicle to effect an elevation of the same.

In practical operation, the automobile or 4 3 upon the tracks 3, the axles or the hubs, as may be, being alined vertically With the crutches 29. By the means of the hand wheel 27 rotatory movement may be imparted to the drive shaft 6, the drive shaft 6 actuating the beveled pinions 8, the same meshing into the beveled pinions 9 imparting rotatory movement to the auxiliary shafts 10, the pinions 14 of which, meshing into the pinions 15, will impart rotatory movement to the supplemental shafts 16, the worms 25 upon the supplemental shafts l6 meshing into the worm wheels 2% and serving to rotate the stub shafts 23, pinions 26 of which, meshing into the racks 27, will effect an elevation of the rack bars '28, so'

that the crutches 29 will engage with the vehicle, and lift the same off the tracks 3, the

vehicle being held thus suspended, to the end that the Weight of the vehicle may not a be borne by the tire when the vehicle is not in use,

Having thus described the invention what is claimed is 1. In a device of the class described, a support; a casing mounted on the support;

' a standard mounted on the support; a drive shaft journaled in the standard adjacent the top of the standard; an upright auxiliary shaft journaled upon the standard; beveled pinions connecting the upper end of the auxiliary shaft with the drive shaft; a supplemental shaft journaled for rotation in the casing and in the standard; beveled pin ions connecting the lower end of the iary shaft with the supplemental shaf stub shaft journaled in the casing; a worm wheel upon the stub shaft and located above the supplemental shaft; a worm on the supplemental shaft engaging the worm wheel;

lifting member mounted to slide in the casmg and provided with. a rack; and a pinion secured to the stub shaft and meshing into the rack.

2. In a device of the class described,

support, a track spaced fromthe support and having an inclined end cooperating with the support; standards located along side of the track; a drive shaft journaled in the standards adjacent the upper ends of the standards; upright auxiliary shafts journaled on the standards; beveled pinions con -necting the upper ends of the auxilia
